Acromag’s Modbus C Library software greatly simplifies development of programs to interface with Acromag’s BusWorks® and EtherStax® Ethernet I/O products. The library also supports any standard Ethernet Modbus slave device that communicates via Modbus TCP/IP or UDP/IP protocol. This utility is ideal for developers that are unfamiliar with Modbus protocol or the framing of TCP/IP or UDP/IP messages.

The C library makes programming easy and portable by simply linking user code with the provided function calls (below). Most function calls require passing only a few parameters such as the IP address, Modbus register address, and
register count.

Codes | Functions
01 (01H)  | Read Coil (Output) Status
02 (02H) | Read Input Status
03 (03H) | Read Holding Registers
04 (04H) | Read Input Registers
05 (05H) | Force Single Coil (Output)
06 (06H) | Preset Single Register
15 (0FH) | Force Multiple Coils (Outputs)
16 (10H) | Preset Multiple Registers
17 (11H) | Report Slave ID

Example Program

The included example program is menu-driven to help users build Modbus TCP/IP and UDP/IP commands. Menu selections let users configure, read, and write Ethernet I/O slave devices such as Acromag’s BusWorks and EtherStax products.

Users may also leverage this demonstration application into a tool for configuration or test by supplying commands and/or data values in the form of a text file. The program will execute each command in the text file as if it had been typed from the console terminal.

  • Library of function routines simplify communication with I/O modules
  • Function calls provided for a variety of operating systems
  • C source code supplied
  • Demonstration program included
  • Saves development time
  • Ideal for use with Acromag’s BusWorks and EtherStax I/O modules
  • Compatible with any standard Modbus TCP/IP or UDP/IP device
